The MI-PTSE multi sensor combines optical smoke detection, heat detection and microprocessor control with analogue addressable communications. For smoke detection the MI-PTSE incorporates an improved sensing chamber design, linked to sophisticated processing circuitry with smoothing filters. This helps to eliminate the transient environmental noise conditions which can be the cause of false alarms. The sensor's performance is further enhanced by the integration of special algorithms which automatically compensate for contamination of the sensing chamber. This enables the sensor to provide a consistent level of sensitivity and increased immunity to unwanted alarms.
In combined modes of operation both the inputs from the optical and thermal sensors are processed using special algorithms before an alarm decision is made. If the presence of smoke is detected above a threshold value for a period of time, or if the heat sensor detects temperatures above 58°C then an alarm condition will be generated. In "heat only" mode only temperatures above 58°C will generate an alarm condition. The MI-PTSE includes 2 self governing sensitivity settings. Whilst operating in these modes the detector will automatically adjust to short term changes in it's environment, helping to reduce the potential of unwanted alarms through activities within the protected space. In areas where the normal daytime activities are likely to generate unwanted alarms the MI-PTSE can be programmed to operate in a "heat only" mode during the period of occupation and reverting to optical and thermal operation during the unoccupied period. The MI-PTSE offers performance flexibility coupled with superior environmental stability
